散布草

1.導入網(wǎng)格模型

設置切換不同模型

id ???rand($PT)*2

設置一個屬性 把0-1映射到0-4

int@flo = fit(rand(@ptnum),0,1,0,4);

?

?

設置Y軸選擇

?stamp("../copy3", "treerotate", 0)

treescale ??fit(rand($PT),0,1,9,10)

?treerotate ?rand($PT)*360

?id ????????fit(rand($PT),0,1,0,4)

?

多物體instance

?

1.導入需要instance的點

@id = @ptnum;

@pscale = fit(rand(@id),0,1,5,40);

attribrandomize

orient

i@OBJid = int (fit01(rand(@id),0,44));

s@instancefile=sprintf("$HIP/geo/STONE/%s.bgeo. sc",i@OBJid);

instance

geo層級下的instance實例樹木

string instrances [];

push(instrances,"/obj/tree01");

push(instrances,"/obj/tree1");

@instance = instrances[@ptnun%2];
